System Hinge Assembly

1. A system comprising: a housing; a hinge assembly operatively coupled to the housing for rotation of the housing about a hinge axis, wherein the hinge assembly comprises permanent magnets that generate a first magnetic field and a second magnetic field orientable with respect to each other via rotation of the housing, wherein the first magnetic field and the second magnetic field comprise an aligned orientation, generate a clockwise restoring torque responsive to rotation of the housing in a first rotational direction from the aligned orientation, and generate a counterclockwise restoring torque responsive to rotation of the housing in a second, opposite rotational direction from the aligned orientation; and an electromagnetic mover operatively coupled to the housing for rotation of the housing about the hinge axis.

2. The system of claim 1 , wherein the housing comprises a display.

3. The system of claim 1 , wherein the housing comprises solar cells.

4. The system of claim 1 , comprising a base, wherein the hinge assembly is operatively coupled to the base.

5. The system of claim 4 , wherein the base comprises a keyboard.

6. The system of claim 1 , comprising a turntable, wherein the housing rotates about an axis of the turntable.

7. The system of claim 1 , wherein the electromagnetic mover comprises an electric motor.

8. The system of claim 1 , wherein the electromagnetic mover comprises an electric stepper motor.

9. The system of claim 1 , comprising audio circuitry, wherein the electromagnetic mover is operatively coupled to the audio circuitry.

10. The system of claim 9 , wherein the audio circuitry comprises a microphone input and wherein the electromagnetic mover is actuatable responsive to receipt of signals via the microphone input.

11. The system of claim 1 , comprising touch-sensitive circuitry, wherein the electromagnetic mover is operatively coupled to the touch-sensitive circuitry and wherein the electromagnetic mover is actuatable responsive to receipt of signals via the touch-sensitive circuitry.

12. The system of claim 1 , comprising a processor, memory, and operating system instructions stored in the memory and executable by the processor to establish an operating system environment.

13. The system of claim 12 , wherein the electromagnetic mover is actuatable responsive to a change in a state of the operating system environment.

14. The system of claim 13 , wherein the change in the state comprises a transition to a lower power state.

15. The system of claim 1 , comprising a clock, wherein the electromagnetic mover is actuatable responsive to a clock signal of the clock.

16. The system of claim 1 , comprising a movable mass operatively coupled to the electromagnetic mover.

17. The system of claim 16 , wherein the housing comprises an adjustable center of mass adjustable via movement of the movable mass.

18. The system of claim 1 , comprising at least one battery operatively coupled to the electromagnetic mover.

19. The system of claim 1 , comprising security circuitry operatively coupled to the electromagnetic mover.

20. A method comprising: in a system that comprises a housing, a hinge assembly operatively coupled to the housing, wherein the hinge assembly comprises permanent magnets that generate a first magnetic field and a second magnetic field orientable with respect to each other via rotation of the housing, wherein the first magnetic field and the second magnetic field comprise an aligned orientation, generate a clockwise restoring torque responsive to rotation of the housing in a first rotational direction from the aligned orientation, and generate a counterclockwise restoring torque responsive to rotation of the housing in a second, opposite rotational direction from the aligned orientation, and an electromagnetic mover operatively coupled to the housing for rotation of the panel, actuating the electromagnetic mover responsive to a signal to rotate the housing about an axis of the hinge assembly.
